Milwaukee 13/16″ x 16″ x 21″ MX4 4-Cutter SDS Max Rotary Hammer Drill Bit 48-20-3938

REINFORCED CONCRETE DOMINANCE WITH MX4 CARBIDE TECHNOLOGY

When you’re boring deep into structural concrete, hitting rebar isn’t just an inconvenienceit’s a tool-killer. The MX4 4-Cutter SDS Max bit is engineered specifically to eliminate the lock-ups and snapped heads that plague standard masonry bits. By utilizing a solid head carbide design, this bit maintains its structural integrity under high-torque percussion, delivering up to 5x longer life even when navigating through heavy reinforcement. The precision-ground centering tip ensures your anchor placements are exact, while the optimized flute geometry manages heat and dust evacuation to maximize the efficiency of your high-output cordless rotary hammers.

• / Solid Head Carbide construction provides superior durability and prevents head failure when striking rebar.
• / Integrated Rebar Guards act as a shield to protect the bit from binding or shattering in hard aggregate.
• / Optimized Flute Design accelerates dust removal, reducing friction and delivering up to 15% more holes per battery charge.
• / Wear Mark Indicators provide a clear visual reference to ensure the bit still meets ANSI B212.15 requirements for critical anchor fitment.
• / Sharp Centering Tip eliminates bit walk, allowing for precise spot drilling in concrete and metal decking.
